Is there any way to determine which table a row belows to, if I do a
search on the top level table:
e.g. I have a table called BASE. There are two tables which inherit
from BASE called SUBTABLE1 and SUBTABLE2
If I do a SELECT * FROM BASE WHERE blah; how can I tell which table
(either SUBTABLE1
Hi!
CREATE TABLE table1
( d DATE PRIMARY KEY,
amount INTEGER
);
CREATE TABLE table2
( PRIMARY KEY (y,m),
y INTEGER,
m INTEGER
amount INTEGER
);
CREATE VIEW view1 AS
SELECT EXTRACT(YEAR FROM d) AS year, EXTRACT(MONTH FROM d) AS month,
amount
UNION ALL
SELECT * from table2;
Table1
Howdy,
Id like to do (live) link of Oracle table (on win) in Postgres (on RH9

Peter, Thanks a lot!
Unqualified count() cannot use an index because it has to visit all the
rows in the table.
It is only for my test. In my real practice, queries like
SELECT * FROM view1 WHERE year = 2003 AND month BETWEEN 10 AND 12
will be performed.
Then again, I don't quite believe

You're really doing your best to make sure we don't figure out what's

One thing I can see from your EXPLAIN ANALYZE results, though, is

Richard,
You might want to search the mailing list archives for discussion of an
oracle version of dblink - I seem to remember someone saying they were
working on such a thing.
Yes, it'll be out sometime after 7.4. According to their posts in August,
it's in alpha right now and just barely

I don't know if this is the correct forum for this
question but I will start here...
I have a job tracking system that I am developing with
postgresql and mac os x. I have all the pieces in
place (mostly) but i am having a problem with notify..
I am trying to set up things so that two (or more)
You do realize that extract returns a double precision value not an
integer, and it's probably not going to be willing to push clauses down
through the union where the types are different .
Argh! I didn't noticed that. Thanks for the reminder.
Let's do not consider table2 and view1 for this
so anyone listening for notifications on table2 can
ask table2 for the jobno that was updated. then if
they were viewing that jobno, update their display. if
not just ignore the notify.
Pardon me if I make your focus blur!
I believe the implementation for such requirement in an application

You haven't really explained what your problem is. In general I'd not
guess that year = X and month = Y is a useful operation if Y is
different from 1. You'd be selecting a
